Since this was an experiment, I used unbleached flour and followed the directions perfectly in the video here. It turned out great. Crusty outside, soft inside, great sourdough flavor. The kids weren’t all impressed but 3 of them begged for a slice and ate it.
Today, I’m making sourdough starter from a potato. Hopefully it will work since the girls in my Pioneer class want to try it. Next I’ll try no-knead bread from 100% whole grain flour.
